Introduction

Duration: (10 - 15 minutes)

This stage aims to introduce students to the topic of Raw Material and Industry, detailing the knowledge and skills that will be acquired throughout the lesson. This way, students will have a clear view of what to expect and the objectives they need to achieve, facilitating the understanding of the content and promoting a more structured learning.

Context

Start the class by explaining that all the objects around us are made from different raw materials that come from nature. Say that raw materials are the basic materials used to make all kinds of products that we use daily. For example, the wood of chairs, the cotton of clothes, and the minerals of electronics. Emphasize that understanding where these raw materials come from and how they are transformed into products is very important for us to understand the world around us and the work of people in different places.

Curiosities

Did you know that the chocolate we eat comes from a raw material called cocoa, which is a seed from a fruit? And that the pencils we use at school are made of graphite, a type of mineral that is extracted from underground mines? Curiosities like these show how raw materials are transformed into products that we use every day.

Development

Duration: (40 - 45 minutes)

This stage aims to deepen students' knowledge about raw materials, their origins, processes of extraction and cultivation, and their importance for industry. This way, students will better understand how the products they use daily are manufactured and the relevance of different work activities in various locations.

Covered Topics

1. What is raw material?: Explain that raw material is a basic material that comes from nature and is used to make products. Give examples such as wood, cotton, oil, and minerals. 2. Types of raw materials: Detail the different types of raw materials, such as plant-based (cotton, wheat), animal-based (wool, leather), mineral (iron, gold), and energy (oil, coal). 3. Process of extraction and cultivation: Explain how different raw materials are extracted or cultivated. For example, mining for minerals, agriculture to grow food and plants, and livestock farming to obtain animal-derived products. 4. Transformation of raw materials: Describe how raw materials are transformed into products. For example, cotton is transformed into fabric, wood is transformed into furniture, and oil is refined to produce gasoline and plastics. 5. Importance of raw materials in industry: Explain how raw materials are essential for the industry and the manufacturing of products. Provide examples of industries such as textiles, food, petrochemicals, and mining.

Classroom Questions

1. What is raw material? Give two examples of raw materials that you know. 2. How is cotton transformed into a product that we use daily? Explain the process. 3. Why are raw materials important for industry? Give an example of an industry and the raw material it uses.

Questions Discussion

Duration: (20 - 25 minutes)

This stage aims to review and consolidate the knowledge acquired by students during the class, through the discussion of the presented questions and engagement with reflective inquiries. This helps to ensure that students thoroughly understand the content and can relate it to the world around them.

Discussion

• What is raw material? Give two examples of raw materials that you know. Raw material is a basic material that comes from nature and is used to manufacture products. Examples include wood and cotton.

• How is cotton transformed into a product that we use daily? Explain the process. Cotton is grown in fields, harvested, cleaned to remove impurities, and then spun into threads. These threads are woven to form fabrics used to make clothing and other textile products.

• Why are raw materials important for the industry? Give an example of an industry and the raw material it uses. Raw materials are essential for industry because they are the basis for manufacturing products. For example, the textile industry uses cotton as a raw material to produce clothing.

Student Engagement

1. Which raw material did you find most interesting and why? 2. Can you think of a product that we use daily and what raw material it is made from? 3. Why do you think it is important to know the origin of raw materials? 4. How do different work activities (such as agriculture and mining) affect the places they are carried out? 5. Do you know any product made from a local raw material? What is its production process?

Conclusion

Duration: (10 - 15 minutes)

This stage aims to review and consolidate the main points covered in the lesson, ensuring that students have a clear and complete understanding of the content. By summarizing, connecting to practice, and highlighting the relevance of the topic, this section reinforces the learning and practical application of the acquired knowledge.

Summary

• Raw material is a basic material that comes from nature and is used to make products.
• There are different types of raw materials: plant-based (cotton, wheat), animal-based (wool, leather), mineral (iron, gold), and energy (oil, coal).
• Raw materials are extracted or cultivated through processes such as mining, agriculture, and livestock farming.
• Raw materials are transformed into products, such as cotton into fabric, wood into furniture, and oil into gasoline.
• Industry relies on raw materials to manufacture products, such as the textile industry that uses cotton.

The lesson connected theory with practice by explaining in detail how raw materials are extracted, cultivated, and transformed into products that we use daily. Specific examples, like the transformation of cotton into fabric and the use of minerals in electronics manufacturing, helped students visualize and understand the practical application of these processes in everyday life.

Understanding where raw materials come from and how they are transformed is essential to valuing the products we use and the work of people in different sectors. Knowing that chocolate comes from cocoa or that pencils are made from graphite helps us realize the importance of nature and different economic activities in our lives. Additionally, this knowledge can spark students' curiosity about the environmental and social impact of these activities.
